it is ok with VMware 12 workstation Sage7.6 and W10. so it seems the problem comes from Oracle Virtualbox under W10 OS !

( see the last image at the end of the post on microsoft community).I added a youtube video of the crash.this seems crazy but there is no event about the crash in journal event observer of W10.Like W10 don't notice anything !!

As in the beginning I did not know where the problem came from (Sage Math, Virtualbox, W10) I posted on the 3 forums.Now I find it a bit stupid to have to recopy the same information on the 3 forums especially that with your rudimentary forum that does not accept URLs or images I will not be able to explain correctly, because the crash Does not apparently produce a log (maybe there is a log somewhere generated by Virtualbox?). Also you could simply do a Google search with these words: microsoft community crash W10 sage ovanow I know that the problem is beetween Virtualbox and W10.

So, you are expecting people from three different and unrelated forums to work together and solve *your* problem, is that right?

A copy/paste is a stupid action? Man, I should check my IQ then, because the letters "C" and "V" are worn on my keyboard.

It does. And it does. "Yes" on both accounts. URLs you have to be a member for 1 day, cuts down on spam. Images is below the post form, where it says "Upload attachment"?

ortollj wrote:Also you could simply do a Google search with these words

Seriously? Really? You're bored enough to copy/paste and you want everyone to rush and search for your problem? I'm not sure you really have a complete understanding on how this whole "help" and "community" thing really works.

Good. The problem is that *we* don't know what even the problem is, because you didn't bother explaining the most basic symptoms.

Since this thread has dragged for too long, if the next message from you does not include a complete and detailed description of your problem according to the Minimum information needed for assistance, including a complete, zipped VBox.log, I'm afraid I'm going to have to lock the thread.

PS. Just out of a hunch, try to disable Hyper-V in your host.

Thank you and goodbye.Problem description still missing. Locked as promised.
